Abstract (en)
Disclosed is an improvement in a femoral implant (1) for a hip prosthesis involving a longitudinal shaft (3) having a neck (5) extending therefrom at an acute angle theta to the longitudinal direction made of layers of carbon fiber in a polymeric matrix, each layer containing unidirectional fibers and the layers arranged such that carbon fibers are oriented in the longitudinal direction and the +/- theta direction. The improvement involves balancing at least 50% of the layers in the +/- theta direction. <IMAGE>
